{"title":"Droxidopa for Hypotension of Different Etiologies: Two Case Reports.","authors":"Jomi Oommen, Judy Chen, Shan Wang, Thomas Caraccio, Adel Hanna","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>Orthostatic hypotension is defined as a decrease in systolic blood pressure of at least 20 mmHg or a decrease in diastolic blood pressure of at least 10 mmHg (or both), within three minutes of moving from a supine to an upright or standing position. Droxidopa is a synthetic amino acid analog that is directly metabolized to norepinephrine by dopa-decarboxylase, subsequently providing alpha and beta-agonist effects to increase blood pressure. It is indicated in the treatment of neurogenic orthostatic hypotension caused by primary autonomic failure that is associated with Parkinson disease, multi-system atrophy, pure autonomic failure, dopamine beta-hydroxylase deficiency, and/or non-diabetic autonomic neuropathy. In addition, it has been studied in other disease states, such as diabetic autonomic neuropathy-associated orthostatic hypotension and supine hypotension. We report on two cases of off-label droxidopa use. The first case was for diabetic autonomic neuropathy-associated orthostatic hypotension, and the second case was for hypotension due to autonomic dysfunction associated with rheumatoid arthritis. Although the outcomes differed in each case, this article contributes to the literature demonstrating that droxidopa may have varying effects in treating orthostatic hypotension of non-neurogenic etiology.</p>","PeriodicalId":38773,"journal":{"name":"P and T","volume":"44 3","pages":"125-144"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6385736/pdf/ptj4403125.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"37019427","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
